HMRC is closing its free Company Tax Return service
14 May 2025

HM Revenue & Customs (HMRC) will permanently close its free service for submitting Company Tax Returns and annual accounts on 31 March 2026.

Built over a decade ago for simpler businesses, the platform no longer meets modern digital standards.

Companies must now move to commercial filing software to remain compliant.

This software provides more modernised features, including:

• Error checks before submission

• Filing to both HMRC and Companies House in one step

• Alerts, reminders and built-in support.

Make the switch before it disrupts your next deadline

The changes are not due to take place until next year, but if you prepare now, it allows you to test the new system, reduce the risk of errors and late filings, and avoid any last-minute scrambles before the deadline.

If you haven’t already, you should review your current processes, choose HMRC-compatible software, and set up your system well ahead of time.

You do not need to notify HMRC or Companies House when you switch.

Prepare for the deletion of old tax returns

After 31 March 2026, you will no longer be able to access previously filed returns or amend them online.

You should download and store at least three years of records. Any changes after this date must be made using software or by post.

If appointed as your agent, we will be able to action this on your behalf.

Dormant companies still have duties

Even if your company is inactive, you must file annual accounts with Companies House.

Corporation Tax may not apply, but that does not remove your reporting obligations.

This includes:

• Charities

• Flat management companies

• Amateur sports and community clubs
